HABITAT TYPES AND PLANT COMMUNITIES : 
Leatherleaf is a dominant shrub in seral dwarf-shrub wetland communities
[15,16,48].  Leatherleaf occurs in pure stands on floating mats and in
mixed stands that are grounded [33].  Leatherleaf associations are the
most extensive communities in the bogs of the Lake States.  Several
subtypes of leatherleaf associations have been described for New England
peatlands [20].  Sphagnum-leatherleaf community types have been
described for this region and Canada [17].  Leatherleaf is usually
present in the tall-shrub community types of bogs or heathlands [20,76].
In central and northern Canada, leatherleaf has been included in various
open black spruce (Picea mariana) vegetation types [17,43,49,73].

Leatherleaf is named as a dominant or indicator species in the following
classifications:

(1)  Ecology of peat bogs of the glaciated northeastern United States:
       A community profile [16]
(2)  Community classification of the vascular vegetation of a New
       Hampshire peatland [20]
(3)  Plant communities of Voyageurs National Park, Minnesota, U.S.A. [48].

Species associated with leatherleaf that are not mentioned above are
codominant shrubs such as bog kalmia (Kalmia polifolia), sheep laurel
(K. angustifolia), bog labrador tea (Ledum groenlandica), blueleaf
bog-rosemary (Andromeda glaucophylla), bog cranberry (Vaccinium
oxycoccos), and sweet gale (Myrica gale) [20,48,55,73,76].  Other
species occurring with leatherleaf are roundleaf sundew (Drosera
rotundifolia), pitcherplant (Sarracenia purpurea), and sedges (Carex
spp.) [16,17,39,48].
